GUSTAV CHRISTIAN NUESEEE, OF HEBBING, MINNEfiQTAQ Application filed April 25,

T 0 aZZ whomit may concern:

Be it known that .l, ii-us'rav C. NUESSE, a citizen of the United States, residing at llibbing, in the county of St. Louis and State of lviinnesota, have invented certain new and useful Improvements in Loaders; and I do declare the following to be a full, clear,and enact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to devices for loading and unloading purposes and has forits object to provide an extremely simple and inexpensive, yet highly eiiicient,easily operated and rapid device which may be opcrated by one man, for instance for loading and unloading cars.

ln-the accompanying drawings, forming a part of this specification;

Figure 1 is aside elevation of a loader constructed in accordance with my invention.

Figure 2 is a front end elevation.

Fig-lure 3 is a vertical sectional View with parts in elevation.

'- Figure 41 is an enlarged sectional view through the upper and lower ends of the vertical standard, and associated parts.

Figure 5 is an elevation, partly in section of the standard and its clamping means.

Figure 6 is a horizontal sectional view as indicated by line 6-6 of Fig. 3.

Figure '7 is a detail vertical section as indicated by line 7-7 of Fig. 6.

In the drawings above briefly described, the numeral 1 designates a vertically disposed cylindrical standard having threaded bores 2 in its upper and lower ends, into which screws 3 are threaded, the outer ends of said screws being provided with plates l which are preferably swiveled thereto as indicated at 5. The screws 3 are provided with appropriate handles 6 whereby they may be rotated to force the plates 1 against the floor and ceiling of a car, a mine, or the like.

Rotatably surrounding the standard 1, is a sleeve 7 whose lower end is here shown resting on ball-bearings 8 supportedby an outstanding flange 9 on said standard, while roller-bearings 10 are illustrated between the upper ends of said standard and sleeve. By mounting the sleeve in the manner disclosed or in a similar manner, it may be turned freelyupon the standard 1 and for Specification of Lettersiatent. Patented May 16, 1922'.

so turning Said v 1 provide the latter with horizontally extending handlelll. As shown, this handle is provided with a spring-pressed latch rod 12 whlch extends through an opening 13 in the sleeve 7 for engagement withany one of a plurality of sockets l t with which'the standard 1 is provided. It will thus be seen that when'sleeve 7 is once turned, it maybe locked against further movement.

' At its lower end, with an outwardly extending vertical flange 15 to which a pair of inclined bracebars 16 are secured, the upper ends of said brace the sleeve 7 is provided" bars being spaced outwardly from the sleeve a 7 and tied to the latter by appropriate tie preferably diverge suiliciently to straddle In the angle between the brace said support as shown in Fig. "2 thereby formin an effective brace and holding means ror the outer end of said support, the innerend of the latter being appropriately secured to the sleeve. 1

A telescopic boom .19 is pivoted atIQO'to the sleeve 7 and is positioned to swing vertically between the brace bars 16, said boom being preferably formed of tubular section 21 which 1s plvotally mounted and another, section 22 sliding in said. tubular section and carrying an appropriate bucket 23. By adjusting, the'section 22 within the sec tion 21, the length of the boom may be in creased or decreased as required, and to prevent either the compression of air or the formation of a vacuum in the section 21 while these adjustments are being made, said section is provided with an appropriate vent 24. After adjusting the section 22, it may be held by any preferred means, such as a set-screw 25. i I

I have shown a cable 26 leading upwardly from the bucket 23 over a sheave 27 mountedv at the juncture of the braces 16 and tie-bars 1?, said cable then extending inwardly over a sheave 28 on the pivot 20, from which sheave it depends to an appropriate drum 29 driven by an electric, pneumatic or other motor 30 mounted on the support 18. By operating the drum 29, it will be seen that the cable 26 may be wound or payed out to raise and lower the bucket 23, and by means of the handle 11, the sleeve 7 may be turned on the standard 1 to swing the boom 19 and associatedparts, to any required position.

The bucket 23'may be provided with any suitable dumping bottom controlled by a hand rope 31 Or any other suitable-means.

All of the controls which are necessary for operating the machine are preferably located adjacent the motor support 18 so as =to' be-readily-within reach of the operator who may manipulate also the handle 11. Thus, one man is enabled to rapidly load or unload cars or the like and a great saving in time and labor is effected. Obviously, the

length the boom 19 may be increased or decreased as occasion may require, the set-- screwv25 serving to hold the sections 21 and 22 against relative movement-after the ad justment has been made.

'The device is extremely simple and inexpensive, yet will be highly efiicient and desirable and may be so constructed that by merely removing afew bolts, the entire structure may be knocked down for easy carrying from place to place.

Since. excellent results may be obtained from the details disclosed, they may well befollowed, but within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. 'A deviceot the class described comprising a vertical standard having clamping screws at its upper and lower ends, a

'verticalsleeverotatably surroundin said standard, a handle extending from said sleeve for turnlng the same, a load-raising boom, pivoted to said sleeve, a frame structure supported by said sleeve and carrying cable. guiding means, a hoisting cable for said boom trainedover said cable guiding means, a motor support carried by said frame structure and sleeve, a motor mounted on said support, and a motor driven drum upon which said hoisting cable is wound.

2. A device of the class described comprising a vertical standard having clamping screws at its ends, a vertical sleeve rotatably surrounding said standard and supported thereby, a pair of brace bars secured at their lower ends to the lower end of said standard and inclining therefrom, tie-bars connecting the upper ends of said brace bars with the upper end of said standard, a boom operable between said brace bars and pivoted to said sleeve, a sheave at :the uncture or" said brace bars and tie-bars, another sheave atthe pivot of said boom, a hoisting-cable trained over said sheaves and connected vith said boom, a horizontal motor support in theangle between said sleeve and said brace bars and jointly supported thereby,

said sleeve, rigid handle extending laterally from said sleeve for turning it upon said standard, a latch associated with said handle and passing through said. sleeve, and

means carried by said standard to co-act with said latchand hold said sleeve in adjusted position.

In testimony whereof I have hereunto set my hand.

GUSTAV CHRISTIAN N UESSE.
